Language has gaps. Both people and A.I. fill in those gaps. The difference is awareness. Computers have none so they’re just pulling statistically likely phrases from their dictionary. Then the programmer might note the ambiguities and ask for verification, but at no time does the computer know what it’s talking about.

Why would I set up an assistant that’s just like me? I’m too lazy to do much myself. A MiniMe wouldn’t be any better; in fact, if it had the power of today’s computers behind it, it might just be even lazier, and, being smarter, con me into doing stuff for it.
